To all 401mm it ma 0mm i i i Begit known that we, CON RAQMI LL ERand JOSEPH BOLDON,- o f the. city of Pittsburg, in

the county ofAllegheny and State of Pennsylvania, have inventeda new and useful Improveinent in Machine .for Flanging jBoiler- Heads, .whichdmprovement is fully setforth in the followingspecification andaccompanyis to rapidly disk, so that The. object of ourzinventionjustable tothe diameter-and thickness there of, and size of flange required .for boiler or other headsdrawing, to which reference. is had.v A

In the drawings, A is a heavy bed-plate, to which all the parts attach. B is a circular revolving table, the-diameter beingsuch as to allow the smallest-sized head the machine is intended to work (about fourteen inches) to project the width of the intended flange all around. Said table is fast on shaft B, which is journaled at its lower end in the bed-plate A, and also just below the table, in the bearing b 0 is a large bevel-wheel on shaft B, which is driven by its companion wheel 0, on the main shaft D, said wheels revolving the table B on the upright shaft B. Motion or power is communicated to the machine by a driving-pulley on shaft D. E is a gearwheel fast on main shaft D, between the bedplate and driving-pulley D. (See Fig. 1.) H is an arm with straight and curved portions, the former provided with an aperture in its end to embrace loosely the shaft D, and the latter with a curved slot, h, throughout its extent, to enable it to slide on the screw 0. F

is a shifting-wheel, fixed to the elbow of said arm, so as to be raised or lowered to mesh with wheelG when the machineis set'; to flange disks of. different sizes. Havingbeen adj ustedto any given position the arm. isgfixed by the screw. e4; 1 Iare ways on each side of the table, and at about the. same-elevation above the bed-plate, bein g supported by strong posts or frame-work connected to the bedplate A. These ways are longitudinally and horizontally slotted. In these slots are placed the sliding blocks l"l,;at the front endof which the swinging. carriage Jis pivoted or journaled'.- This carriage must be made very strong, and is of the form shownin Fig.3. It

, carries the roller-frame K, in which are journaled the rollers LL.

The pillow-blocks k 16 slide lon gitudinall by the screw 9', having the buttonl, by which the-rolls can be projected from theffront end of the frame K toward thetable B. .Gonnected to and descending from eachside of frame K are twocogged segments, M M. ,(See Fig 2.) .Directly'b'ack of the carriage J is-the shaft-N, ha vingits journals in the sliding blocks IsI.

Fast on this shaft; are two pinions, P B, the teeth of which mesh into the teeth of these'gfmenfts MM. On the right-hand endoftthis shaft, outside'ot' rail I and in line-withwheel a F, is a large gear-wheel, G, the teeth .of which meshinto said. intermediate wheel "when in proper positiohfand which, through said intermediate wheel, receives motion from wheel E on main shaft D. g g are two screws, operated by thebevel-wheels h hi '5, and small shaft m and crank n, by the action of which, it will be seen by reference to Figs. 1 and 2, the rolls, carriage, and shaft N are moved to or from table B, and it is obvious that when shaft N is movedback, wheel G would also move out of connection with wheel F. When this is the case the arm H is moved up that the intermediate wheel F will connect again. 0 is an L-shaped supporting-post, the short arm of which bears on the bed-plate, grooved to receive a lug from the under side of the said short arm, through which passes a screw, so that the post may be moved to or from the table, as the slides I I are. The long arm projects up to even height with table B, where it extends in width and is concave on its face yin said frame, being moved to correspond to the edge of the table B, its use. being to. support the edge of large disks at the'point just in front of the rolls.

R is a head which revolves in the bearing 7 and on the point 8, and is connected to the screw S by the v cap R, which turns loosely on' its upper head or boss U. (See Fig. 2.) The screw S passes through the cross-bar S, and, by its head U acting in the cap R, raises the head R or lowers it on the boiler-head or disk to hold it firm on table B. T is a crankwheel on screw S. A jam-nut by which the screw may be prevented from turning may be used above cross-bar S.

Operation: The disk of iron to be flanged is placed on table B, and adjusted to project evenly. The head It is then screwed down by the screw S and "fixed by the jam-nut from turning. Supporting-post O is then moved forward by turning the adjusting-screw to support that portion of the diskfwhich is to form'theflan'ge. v The sliding blocksI I are then moved forward by means'of the screws g g, crank it, shaft m, and bevel-wheels h t h i, bringing the carriage and rolls up to the disk, and the rolls being in a horizontal position the edge of the disk passesbetween them. The intermediate wheel F is now raised into such position that the teeth will mesh into wheel G, and if it is found that they do not properly; interlock the slides I I, which carry wheel I G, .may be moved back or forward. When wheel F is thus properly adjusted with wheel G it is made fast by the screw 6. Then the rolls are nicely adjusted to the desired size of the required flange on the disk by the screw and crank j l. v t

("The machine is now put in motion, and, as the table? and head 1% revolve, the edge of the disk passes between the rolls L L, which revolve by friction, and the gear-wheels receiving motion from the shaft 1) communicate it to the pinions P P, which begin to elevate the frame K and the rolls from a horizontal to a perpendicular positi0n,"or, in other words, to change their position to a right angle to the the object set forth.

table and disk, and the edge of the disk being between the rolls is gradually bent up into a flange. When the flange is bent to a right angle the motion of the segment ceases as the number of cogs on it are made with relation thereto. v v v v i By reference to the drawings it will be seen that the movement of the carriage J on its axis is very slow compared with the movement of the table B.

Having thus described our invention and its operation, what we claim, and desire Letters Patent for, is-

v 1. The revolving table B in combination with shaft B and the rolls L L, all constructed and operating as described, for the object setforth. V 2. The rolls L L, frame K, segmentsjM M, carriage J, and revolving table B, all coma bined, constructed, and operating as described, for the object set forth. 1

3. In combination with the segments M M, the pinions P P, gear-wheels E F G, as described, and for the object set'forth. g e

4. The adjustable support 0 in combination with the revolving table B and the rolls L L, for the purpose of supporting the edge of the disks, when being flanged, which are of greater diameter than can be supported by the table, as described. p

5. The sliding blocks 1 I, adjusting-screws g g, shaft m, wheels 1' hilt, and crank n, in combination with the carriage J, constructed and operating as described. v j

6. The combination of table B, upright shaft B, wheels O 0, main shaft D, wheels E F G, arm H, carriage J, frame K, rolls L L, segments-M M, shaft .N, supporting-post 0, pinions .P P, slides I I, adjusting-screws j g, all constructed and operating as" described,lfor
